Can't say we're surprised this happened. Apple has sued Samsung to block sales of the company's Galaxy S III smartphone in the United States. They are looking to receive an injunction on the grounds that the Galaxy S III infringes on at least two Apple patents.

The complaint was filed in a California court earlier this week and posted online by patent law blogger Florian Muller, the Galaxy S III clearly infringes on data-tapping and unified search technologies owned by Apple.

Samsung, unsurprisingly, is having none of that.

“Samsung believes Apple’s request is without merit,” a Samsung spokesperson told the Los Angeles Times in a statement. “We will vigorously oppose the request and demonstrate to the court that the Galaxy S III is innovative and distinctive.”

Considering their long spat with one another, we'd think Samsung would be a bit more careful this time in avoiding any infringement. Apple's move to block the Galaxy S III in the U.S. is just the latest in a long line of patent disputes between the two. Last month, the Cupertino company filed a motion against Samsung over its Galaxy Tab 10.1 tablet.

Samsung unveiled the Galaxy S III at the beginning of May during an event in London. Perhaps the most anticipated Android handset this year, it’s the third generation of Samsung’s popular line of Galaxy smarthphones.

The S III runs on Android’s latest Ice Cream Sandwich operating system and features a 4.8-inch touch screen, 8-megapixel rear-facing camera and 1.9 megapixel front-facing camera.

Apple’s Galaxy S III complaint cites press reports saying Samsung has already sold more than nine million preorders of the device — meaning it could cause “irreparable harm” to Apple.

What do you think? Does Apple have grounds in this? Or not? Either way, Samsung's already gone off quite far already, and nine million is just the beginning.
